From Susan Boyle to Jonathan Antoine, unexpected greatness has been a part of reality television and talent shows. It was no different when shy 19-year-old make-up artist Andrew De Leon, pulling off the goth look to a T in all-black clothing, black eyeliner and pale contacts, dazzled the America's Got Talent crowd and audience last night, bringing girls to tears as he sang, of all genres, opera.

What makes Andrew De Leon's performance, which can be viewed in the video below, even more remarkable is that Tuesday's America's Got Talent marked the first time the shy and unconfident teen performed in front of anyone.

Growing up, I was a huge fan of Marilyn Manson, Rob Zombie and all these different rock stars. They really became an escape for someone like me, who felt that I was an outsider, he told the America's Got Talent cameras in his pre-performance interview as Ozzy Osbourne's Dreamer played in the background. Growing up, I was alienated because I was never interested in athletics or what everybody else in my family was interested in.

Andrew said singing was always an escape for him.

Being on 'America's Got Talent' is a huge step for someone like me, who's never sang in public before, never sang even in front of my family, he said.

The 19-year-old make-up artist said he believed his appearance on America's Got Talent would help him get out of his shell.

I think my days of being shy and being an outcast have reached their end, and I'd like to be able to really show what I can do, Andrew De Leon said.

As the first notes of Andrew's song played, judge Howie Mandel gave a look of incredulity, not being able to believe that a teenager with a goth look was about to pull off opera.

But within seconds, it was apparent that Andrew had the talent that the show was seeking, as NBC panned to views of girls with tears in their eyes from Andrew's singing.
